So glad you liked it! The angel is needed to teach the child how to fix/where to put each item (the “investigate” option only shows for the angel and is needed for the child to collect or fix it). The picture is just there for some extra lore and to make the inventory slots a little more valuable since you only get 2. But since there’s only really 3 things you can collect I can see why it feels a bit random - maybe with even more non-essential items it would make the puzzles and winning a bit more challenging. Thanks for playing and for the feedback! :)
